tweet air / fuel intake screw to stop stalling

Post by robyn131 on Wed 10 Oct 2018, 1:10 pm

Hi,

My bike has started stalling when in neutral, either on tick over or coasting. I want to tweet the air/fuel intake to increase the tick over revs but haven't done this before. 

I can see 2 brass screws on the underneath engine side of each carb and 1 big yellow turn knob in-between the carbs. Does anyone know which one is which (air/fuel) and any recommendations on how to go about increasing idle revs?

Thanks

Robyn the big yellow turn knob is for tickover adjustment. If you cant get your fingers in just push it round with a screwdriver. The two brass screws are idle mix adjusters and apart from a bit more science being involved they ae really easy to knacker (I speak from experience!)

What is the current idle rpm setting - it should be about 1300rpm +-100.

Screwing in will increase revs.
